Description

The present invention relates to a size adjustment insole and a size adjustment insole that can be adjusted to correspond to the size of each user's foot when selling or purchasing shoes.

Conventionally, footwear such as shoes, sandals, high heels and the like are generally mass-produced with each manufacturer determining the size based on a predetermined standard regarding the foot length and width of the shoes.
Therefore, depending on each manufacturer, manufacturing method, etc., even for the same size, the user may be cramped, loose, or just fit on the foot, and sometimes shoes that fit the user's own foot may not be available. . In order to eliminate such inconsistencies in the size of shoes and feet, proposals have been made to deal with various variations in insoles. As an example, there is one shown in Patent Document 1, for example. This is intended to enable the use of various variations according to the type of shoes worn by the user. For example, a shoe insole consists of multiple parts, a thick heel part that lays thick from the arch to the heel, a thin heel part that lays thin from the arch to the heel, a front lay part that lays from the arch to the toe, And a padding portion for filling a space formed between the finger and the shoe. The thick heel part and the thin heel part have a shape in which the arch portion becomes thinner toward the front, and the front laying part has a shape that becomes thinner toward the rear, and these three parts overlap each other on the arch. In the state, a smooth surface is formed. The front laying portion has a step, and the front end of the thick heel portion or the thin heel portion is shaped to fit into the step. Then, the thicker heel portion, the thinner heel portion, and the laying portion are integrally molded and then separated.

  However, the conventional insole is composed of a plurality of parts, and the entire insole is constituted by a combination thereof, so that the structure is complicated and fine adjustments such as height cannot be performed. There is a bug. As a result of earnest research on the relationship between the user's foot and the shoe that is the footwear, the present inventor has devised an insole that can be adjusted in size so that the shoe is more comfortable by fitting the shoe to the user's foot more finely. SUMMARY OF THE INVENTION An object of the present invention is to provide a size adjustment insole capable of adjusting the comfort of each user or adjusting the foot size when selling shoes or purchasing shoes. There is.

  In order to solve the above-mentioned problems, the present invention provides a plate-like insole body having a planar shape substantially matching the shape of the inner bottom surface of a shoe, and a foot on the surface of the insole body. A raised part corresponding to the arch is provided at the place where the arch part of the back is located, and the back side of the toe side from the heel to the back side of the place where the raised part corresponding to the arch is provided in the middle of the planar shape of the insole body The gist of the present invention is that a size adjusting insole comprising an additional sheet affixed is provided. A plurality of the additional sheets can be attached, and can be attached and detached.

  In the size adjusting insole of the present invention, the additional sheet is formed so as to have substantially the same planar shape as the planar shape of the insole body on the toe side from the substantially center line in the front-rear direction of the planar shape of the insole body. In addition, for multiple additional sheets affixed to the back surface of the insole body, the next additional sheet is affixed on the additional sheet directly affixed to the back surface of the insole body, and the next additional sheet is further added to the additional sheet. It is preferable that the additional sheets are sequentially stacked and pasted so that the sheets are pasted. Further, the additional sheets are set so that the front-rear direction dimensions of the additional sheets are sequentially shortened from those attached directly to the back surface of the insole body to those attached to the part farthest from the back surface of the insole body. And it is preferable that the short dimension edge part of the additional sheet stuck inside is exposed. Thereby, when peeling the additional sheet affixed on the insole body, it can be easily peeled off one by one. Furthermore, the plurality of additional sheet affixing portions that are sequentially affixed to the back surface of the insole body penetrate from the front surface of the insole body to the additional sheet that is affixed to the part farthest from the back surface of the insole body. Ventilation holes are preferably formed. This prevents stuffiness in the shoe and prevents the additional sheet from being easily peeled off.

  According to the size adjustment insole of the present invention, the thickness of the insole can be adjusted by a small dimension for each sheet thickness by peeling off or additionally attaching the additional sheet. It is possible to adjust the size so as to correspond to the size of each user's foot wearing the footwear.

    Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3 show an embodiment of the present invention. FIG. 1 is a front view of a size adjustment insole according to the present invention, and FIG. 3 is a back view of the size adjustment insole according to the present invention. FIG. 3 is a cross-sectional view taken along line AA in FIGS. Reference numeral 1 denotes a size adjustment insole (hereinafter simply referred to as “insole”) according to the present invention. The insole 1 has a planar shape that substantially matches the inner bottom surface of the shoe, has a predetermined thickness, and has a somewhat supple plate-like insole body 2 and a back surface of the insole body 2. Is the same shape as the insole body 2, and is formed by attaching an additional sheet superposed body 3 in which a plurality of additional sheets are bundled in a peelable manner. The surface of the insole body 2 has a shape corresponding to the depression of the arch at the location where the arch part of the foot is located, and the surface is made flat by using a material with some flexibility and the surface is swollen There is a case where a bulge member 6 which is a arch butt member which is formed into a mold is disposed. As described above, the insole body 2 does not need to have a planar shape that completely matches the inner bottom surface of the shoe, and has a shape that can be inserted into the inner bottom surface of the shoe as a conventional insole with a certain margin. It is dimensioned in the same way. The insole body 2 of the insole 1 according to the present invention, which is made by combining the additional sheet superimposing body 3 and the bulging member 6, is formed on the outside of the insole body 2 in order to match the inner bottom surface of the shoe. There may be a configuration in which a predetermined width can be cut along the periphery.

As shown in FIG. 2, the additional sheet superimposing body 3 is attached to the back of the insole body 2 as a bundle in which a plurality of additional sheets 3a, 3b, 3c,... 3n formed in the same shape as the insole body 2 are superimposed. In addition, a plurality of additional sheets 3a, 3b, 3c,... 3n pasted as a bundle are overlapped so that each additional sheet 3a, 3b, 3c,. A bundle. In addition, the additional sheet superimposing body 3 in which a plurality of additional sheets 3a, 3b, 3c,... 3n are overlapped and attached to the back surface of the insole body is the back side of the place where the bulging member 6 is disposed. The additional sheets 3a, 3b, 3c,... 3n superimposed as a bundle are cut in the width direction of the insole body 2 and added to the additional sheet superimposed body 3X attached to the heel side and the additional sheet superimposed body 3Y attached to the toe side. A notch 5 that is half-cut reaching the back surface of the insole body 2 may be provided so as to be divided into two.

  Each of the plurality of additional sheets 3a, 3b, 3c,... 3n forming the additional sheet superposed body 3 is a thin sheet made of a flexible material, and is made of a material that does not easily tear or tear. It is natural to use. Further, in order to obtain a superimposed additional sheet 3 in which a plurality of additional sheets 3a, 3b, 3c,... 3n are bundled, the additional sheets must be bundled in a superimposed state so that they can be easily peeled off. The state is formed by applying a weak adhesive to the back of each additional sheet 3a, 3b, 3c,... 3n, or by a known means for heat-bonding a heat-weldable sheet with a release sheet interposed. Also good.

An additional sheet superimposed body 3 in which a plurality of additional sheets 3a, 3b, 3c,... 3n attached to the back surface of the insole body 2 are stacked on the additional sheet 3a directly attached to the back surface of the insole body 2. The additional sheets 3a, 3b, 3c,..., 3n are sequentially stacked so that the next additional sheet 3b is pasted and the next additional sheet 3c is further pasted on the additional sheet. .

When using the insole 1 formed by combining the above-described members, the insole 1 may be used as it is in the conventional manner. However, as described above, the additional sheet superimposing body 3 is provided with the cut 5 by the half cut. When it is assumed, a plurality of additional sheets obtained by folding the portion where the notch 5 is provided, that is, the middle side of the insole body 2 in two, and overlapping the above-mentioned half-cut notch 5 in the overlapping state as described above. 3n, 3a, 3b, 3c,..., 3n are divided into an additional sheet superimposed body 3X positioned on the heel side and an additional sheet superimposed body 3Y positioned on the toe side at the above-described locations. At this time, it is desirable that each superimposed additional sheet is half-cut so that the cut edge that is divided into two forms a minute step as shown in FIG.
For this purpose, the half-cut is not a half cut perpendicular to the insole body from the surface of the additional sheet superimposed body 3 superimposed as a bundle, but from the surface of the additional sheet superimposed body 3 It is desirable to half-cut at an angle inclined with respect to the angle.

In using the insole 1 according to the present invention, after the operation of dividing the additional sheet superimposing body 3 into two as described above is performed, the bending of the insole body 2 is restored to make the insole body 2 flat. Return to the main body 2. This is used as the insole 1. Since this additional sheet superimposing body 3 is half-cut in the state described above, a plurality of additional sheets 3a, 3b, 3c,. From the additional sheet 3a directly attached to the back surface to the additional sheet 3n attached to the part farthest from the back surface of the insole body, the dimensions of the additional sheets 3a, 3b, 3c,. The front-rear dimension of the additional sheet 3b is shorter or longer than the front-rear dimension of the additional sheet 3a, and the front-rear dimension of the additional sheet 3c is shorter or longer than the front-rear dimension of the additional sheet 3b. The half-cut surface of the additional sheet superimposing body 3, that is, the cut-in 5 surface is set to the end sides of the additional sheets 3a, 3b, 3c,. It would be exposed as an edge portion 4, as shown in FIG.

Further, the additional sheet superimposed body 3 attached to the insole body 2 is formed with a vent hole 3A penetrating the insole body 2 as shown in FIGS. In addition, although not shown in the drawings, the insole body 2 may be formed by arranging small protrusions that exhibit a finger pressure function. 1, 2, 5, and 6, reference numeral 6 denotes a bulging member that is an arch disposed on the surface of the insole body 2.

About the insole 1 which consists of this structure, the usage at the time of use and an effect | action are demonstrated below.
Shoes made by each manufacturer on the basis of a predetermined standard are made with a large part called the toe part of the toe part. Even when a shoe purchaser finds a shoe with a design that he likes from among the shoes displayed at the store, he / she has a hard time finding a shoe that matches the size of his / her foot, and this cannot be found. We often experience that. This phenomenon is not favorable for the shoe purchaser and the seller.
The insole according to the present invention has been developed to cope with this inconvenience.

  As shown in FIG. 4, when the user places the insole 1 on the shoe 7 and wears the shoe 7, if the shoe 7 fits the foot, a comfortable comfort can be obtained.

When the size of the foot and the size of the shoe are substantially the same, the additional sheet superimposed body 3X affixed to the heel side of the additional sheet superimposed body 3 affixed to the back surface of the insole body 2 of the insole 1 according to the present invention. Then, an appropriate number of additional sheets are peeled off from the additional sheet superimposed body 3Y attached to the toe side and used in the conventional manner.
When using the insole 1 according to the present invention, when it is not necessary to adjust the depth of the collar portion, the additional sheet superimposing body 3X on the collar side from the half-cut incision 5 as shown in FIG. Remove from the insole body 2 before use. The toe of the shoe is made with a certain amount of space, which is called a throw-away dimension. If you are concerned about the clearance of the toe portion when you wear shoes, you can use it by bending the tip of the insole 1 according to the present invention to eliminate the clearance.

  In addition, when the shoe 7 does not fit the foot and the instep portion of the shoe hits the inner ceiling surface of the shoe, the toe side additional sheet superimposed body 3 affixed to the insole body 2 of the insole 1, that is, 3Y The thickness of the additional sheet superimposed body shown is reduced to cope with it. In that case, among the plurality of additional sheets 3a, 3b, 3c,... 3n in a superposed state, first, the uppermost additional sheet 3n of the additional superimposed body 3Y is peeled off. At this time, the plurality of additional sheets 3 a, 3 b, 3 c that are sequentially attached to the back surface of the insole body 2 are the most from the additional sheet 3 a that is directly attached to the back surface of the insole body 2 to the back surface of the insole body 2. Depending on the way of half-cutting over the additional sheet 3n affixed to a remote site, each additional sheet depends on whether the cut 5 is directed toward the heel as shown in FIG. 5 or toward the toe side (not shown). 3a, 3b, 3c,... 3n, the longitudinal dimension of the upper superimposed sheet is shorter or longer than the longitudinal dimension of the lower superimposed sheet 3Y. Since the cut edges that are set differently and are heat-cut are exposed, the additional sheets can be easily peeled sequentially. As a result, the thickness dimension of the insole 1 is reduced by the thickness dimension of the additional sheet at a portion closer to the toe than the substantially center position in the front-rear direction of the planar shape of the insole body 2. Even in such a case, if the inner ceiling of the shoe hits the instep part, the additional sheet of the insole 1 is made thinner. In that case, the additional sheet of the remaining additional sheets is peeled off. Accordingly, the thickness dimension of the insole 1 is further reduced by the thickness dimension of the number of additional sheets peeled off at the toe side portion of the insole body 2. By repeating this process, the inner ceiling of the shoe does not hit the instep portion so that the shoe 7 fits the foot.

  Further, in order to adjust the depth of the heel portion, as shown in FIG. 6, the additional sheet attached in the overlapped state attached to the heel side 3X side of the insole body 2 is left without being peeled off. As described above, the depth of the heel portion of the shoe can be adjusted by removing the additional sheet attached in the state as much as necessary for adjustment. The insole 1 of the present invention is easy to wear because the bulging member 6 is arranged at the location where the arch of the insole body 2 is located, and the vent hole is perforated to prevent stuffiness, and Since the small insole is scattered in the insole body, the acupressure effect is exerted on the soles of the foot during walking.

Conversely, if there is a gap between the instep and the inner ceiling of the shoe, an additional sheet 3 is added to the insole 1 to take measures. In that case, an additional sheet (3d; not shown) is added to the plurality of additional sheets 3. As a result, the thickness dimension of the insole 1 is increased by the thickness dimension of the additional sheet 3d in the portion of the insole body 2 on the toe side from the substantially center line in the front-back direction of the planar shape. By repeating the addition of the additional sheet, the gap between the instep portion and the inner ceiling of the shoe becomes good, and the shoe 7 fits the foot. As described above, even a shoe that does not fit in the size can be made comfortable with the insole 1 of the present invention.
Although not shown, the insole body of the size adjusting insole according to the present invention has a configuration in which the heel portion has a thickness with a depth inclined inward along the heel portion side, or the heel portion. By configuring the cushion member to have an inwardly inclined depth, a size-adjustable insole that is comfortable to wear can be obtained.

  According to the size adjusting insole according to the present invention, it is possible to realize a comfortable shoe by peeling off or adding the additional sheet and adjusting the dimensions of the insole.
